Answer:E none of the above

Explanation:

When a space shuttle orbiting around the earth then earth gravitational force keeps the shuttle in its orbit by providing centripetal force. Tangential velocity makes the shuttle to revolve around the earth. Earth gravitational pull is significant to make the shuttle move in orbit while the Passengers feel weightlessness because they are falling downward but never able to reach as they move fast enough such that earth curves away them.

2 questions that I am just curious about!!! WILL NAME YOU BRAINLIEST!!! Hope you can figure out!! Worth 11 points!!
tensa zangetsu [6.8K]

Answer:

<em>#1:</em><em> Most likely it does so, and calls other paramedics to help the person it was on its way to go help. But usually people will stay out of its way when they hear one coming...</em>

<em>#2:</em><em> Probably, because they usually just don't want meat, and don't have problems with things such as crackers. I doubt that they can live solely from vegetables!! It seems impossible!!</em>

<em />

I have to say they are some quite interesting questions. Interesting to think over... :)  Anyway, I hope my answers help answer yours!!

A spring has a constant k= 10.32 N/m and is hung vertically. A 0.400kg mass is suspended from the spring. What is the displaceme
alukav5142 [94]

Answer:

displacement (x) = 0.003798 meters

Explanation:

from the fact that the string is hung vertically we can deduce that:

Total force acting on the mass = Fs (by spring) + Fg (by gravity)

<em>where</em>

Fs = k*x , x is the displacement..

Fg = m*g

then:

Ftot = m*a, <em>but a = 0 m/(s^2) because the mass becames stationary.</em>

Ftot = 0

Fs + Fg = 0

<em>by direction, take down as negative.</em>

Fs - Fg = 0

k*x = m*g

x = m*g/k = [(0.400)(9.8)]/(10.32)

  = 0.3798 meters

A 0.8 kg bead slides on a curved wire, starting
TEA [102]

Answer:

vB = 12 m/s

W = 36 J

Explanation:

Potential energy converts to kinetic energy

½mv² = mgh

v = √(2gh)

vB = √(2(9.8)(7.1 - 0) = 11.796609... m/s

W = mg(hA) - mg(hB) = 0.8(9.8)(7.1 - 2.5) = 36.064 J
